Which structure is Oracle NoSQL used default? BTree or Hash ?

Hello,
Which structure is Oracle NoSQL used default? BTree or Hash ?
Thank you for your answers.

Oracle NoSQL Database uses Berkeley DB Java Edition as the storage engine. BDB JE only has a b-tree access method.

Which apache does Oracle Apps use?

I'm trying to install vision operations on a suse, but I got the RW-50015 portal is not responding error in the post check, I reviewed the sugestions (java the J2SE edition, the host address, the missing variables in the httpd.conf,ports etc) and nothing is working, I also did as a test a apache installation (the one that came with suse) and this is working fine, so I'm out of ideas! anyone could help me?

Any insight into this issue?
Dapo

Dapo,
Oracle buldles its own module with Apache like mod_ossl, mod_oprocmgr, mod_plsql . It uses Apache 1.3.19 bundled with some of its own modules.
Have you checked whats wrong in error_log at $IAS_ORACLE_HOME/Apache/Apache/logs or is Web Server Up even try to start via scripts mentioned above ?

Oracle NoSQL YCSB - continuously increasing execution time

Greetings,
currently I am testing several nosql databases using YCSB. I am new to that type of databases, but I have already tested few of them. I am using VM with 2GB RAM and hosted on Win 7. Even though it is not recommended, since I am working in now capacity environment, I am using KVlite. But my problem is confusing and I can not find the reason. So, I have successfully loaded data and tested Oracle NoSQL using different workloads. However, with each execution, I get higher execution time. For example, if at 1st execution I get 20 seconds, if I shut database down and next day execute same workload again, I get 35 second execution time and so on.
Do you have any idea of what may be causing that? Like I said, I have been researching some nosql databases but I have never had that strange results.
Regards.

To add to Robert's comment, the NoSQL DB documentation on KVLite states the following:
     KVLite is a simplified version of Oracle NoSQL Database. It provides a single-node store
     that is not replicated. It runs in a single process without requiring any administrative interface.
     You configure, start, and stop KVLite using a command line interface.
     KVLite is intended for use by application developers who need to unit test their Oracle NoSQL
     Database application. It is not intended for production deployment, or for performance measurements.
Per the documentation, you can use KVLite to test out the API calls in your performance benchmarking application, but you should not use to it perform the actual performance testing. For performance testing, please install and use the Oracle NoSQL Database server.

any idea in 10g and 9i ?
thanks in advance.the only way I've found is to search the web for lists of default users and their passwords, then attempt to log on with said credentials. I'd start with Pete Finnigan's site (google is your friend). He may already have some scripts ready to go, or at least the lists you'd need to get started.

How to display message using default lock in ORACLE 9i?

I am using ORACLE 9i I am inserting a same record in a same table (which is having primary key) of same user with different sql editor (or from different machines).
with same time.
One person is able to insert the record..
But other one is in processing state, once the inserted person give commit,then only other person got the message "Primary key constraint voilated".
This is bcoz of concurrency in oracle. For this purpose Oracle uses default lock.
Is it possible to give message to other person like "One user is using this table..", after a record is inserted and before commit is get issued by the inserted user?
how can i do this?
Thanks a lot for your help

Which network is Oracle using for RAC traffic ? where you will get info ? ?

Hi,
I am using two node RAC on Oracle 10g R2 (10.2.0.3.0) version on SUN Solaris 10 . I want to know "Which network is Oracle using for RAC traffic ? where you will get info "
--Kumar

Hi Kumar,
In 10g, you can query x$ksxpia. If the cluster_interconnect information is stored in OCR (default), you will get
SQL> select INST_ID,PUB_KSXPIA,PICKED_KSXPIA, NAME_KSXPIA,IP_KSXPIA from x$ksxpia;
If you specified the cluster_interconnects parameter in your init.ora:
Columns to look in : INST_ID P PICK NAME_KSXPIA IP_KSXPIA
And also you can use 'oradebug ipc' to see which interconnects the database is using:
SQL> oradebug setmypid
SQL> oradebug ipc
Hope it helps...
Thanks

Is it possible to connect Sqlfire server with oracle using DBSynchronizer using default license

is it possible to connect Sqlfire server with oracle using DBSynchronizer using default license
Sql fire is my machine
Oracle is another machine
When i connect sqlfire with oracle using DBsynchronizer It shows the error message as Wan is not supported for default license
When i connect Sqlfie(my system) with oracle( another system) using JDBC Rowloader .nothing is happening after some time it shows the error like"time out for pool connection to archive database.When i increase the time out also nothing is happening.
what is the reason for above two errors(I stated in the pragraph.)
is it beacuse of wan netwrok not supported by default evaluation license?
could you please explain?

I don't think this has anything to do with a VMware product.

Which kerning option do you use in After Effects, and which should be the default?

Which kerning option do you use, Metrics or Optical?
Which do you think should be the default?
How would you feel about us changing the default to Optical and creating a new preference where you can set the default?

OK. Here's where we've ended up for now:
One of our software engineers is working on fixing the bug that keeps the setting from being persistent. So, if you like Optical, you can set it that way once and it will be the default for new text layers created after that.
We're not going to change the default right now. Our thinking is that fixing the bug makes it so that the people who want Optical only need to change it once, and we should continue to match Photoshop and Illustrator with their default. Also, Angie makes a good case that even if Optical is the right solution much of the time, having the default be Optical will cause people to miss out when a type designer has done the right thing and done the pairs correctly for the Metrics case.
We'll revisit this decision if it turns out that our incremental step of just fixing the bug isn't enough to satisfy everyone.
Thanks for the feedback, everyone.

Which Operating system most company use to run oracle?

Which Operating system most company use to run oracle?
thanks

If you are trying to decide on a platform, I would recommend that you look at Swingbench and run your own benchmarks on various platforms using vendor "try and buy" options. Sun is great for allowing a 90 day "try and buy" where you could try a wide range of platforms and I am guessing other vendors would do the same. Using Swingbench I recently found that an older Sun X6220 (blade server) was for 50 Swingbench users faster than a T6340, T2000, M5000 and older V890. Single threaded SQL was especially slow on the SPARC/T while the M5000 was comparable to the X6220 (again for 50 users). This is significant because the M5000 is much more expensive than the X6220 (a blade server).
For a small number of users, say 50 users and under, I like Solaris/x86 unless there will be lots of IO which is where SPARC and the M series scales up very well. 50+ users hammering on a DB, Solaris/SPARC is my first choice. If you are just getting started and are not in love with any platform, check out Oracle Unbreakable Linux.

Which sorting algorithm Oracle use?

Hi ,
May i know which sorting algorithm oracle use ?
Because when i am using order by with an sorted or unsorted data it is taking same time.
Thanks in advance

Please help if any body know because i cant decrease number of rows but i can sorted them in a temp table .Pradeep,
a SORT is usually an additional operation that can be quite costly depending on the amount of data to sort and the available memory for sorting. It would show up in the execution plan as SORT operation.
Note that the optimizer can take various shortcuts to minimize the impact of a sort operation. If you e.g. use a "top-N" query properly, it can take advantage of a "SORT ORDER BY STOPKEY" operation that only keeps the top N rows sorted in memory.
If you have suitable indexes, the optimizer might also come to the conclusion that a SORT operation can be eliminated by traversing an index in the requested order, so you could have a query that uses an ORDER BY but the execution plan doesn't show any explicit SORT operations.
So to answer your question: Oracle doesn't consider sorted and unsorted data in the same way. Sorting is an additional operation that needs to be handled somehow.
If you have a query that takes the same time whether sorted or not the execution time is probably driven by other factors and the SORT operation is negligible in terms of performance.
But there are other scenarios possible where a SORT operation takes significant time and influences the execution time. SORTs can also lead to overall changes in the execution plan that are not directly related to the SORT operation.

Can anyone recommend a good UPK library structure for Oracle financials 11.5.10.2 (using UPK 11.1)?

Hi, Can anyone recommend a good UPK library structure for Oracle financials 11.5.10.2 (using UPK 11.1) please?

If you are using the application server that comes with Oracle Applications - you probably need to use the JDeveloper version that comes with that one too. (The OAF forum will have more info on this).
If you are using JDeveloper 10.1.3 then you can use a stand alone OC4J 10.1.3 to deploy your applications - and save yourself the hassle of messing up with your apps server.

Datastores structure in oracle forms?

Good Morning to all,
I would like to ask if there is any structure in oracle forms, in order to implement datastores which exost in powerbuilder. I hava the following code in powerbuilder :
integer v
if index < 1 or index > 4 then return -1
if isnull( dw[index] ) then
     dw[index] = create datastore
     dw[index].dataobject = dws[index]
     dw[index].settransobject(sqlca)
end if
if dw[index].Retrieve( erg, todate ) <> 1 then
     v = -1
else
     yy = dw[index].GetItemNumber(1,1)
     mm = dw[index].GetItemNumber(1,2)
     dd = dw[index].GetItemNumber(1,3)
     v = 1
end if
return v
which is a function that calculates a variable v, and uses an object (dw) which is a datastore.
Is there in Oracle forms any structire similar to datastore and if there, how can i implement it?
thanx a lot!

So, you can define tables of records.
Declare
-- Block record --
TYPE TYP_BLK is record
    blk_name       Varchar2(30),            -- block name
    blk_idx        Pls_integer,             -- ID of block in collection
    blk_ScrBarPos Varchar2(1) DEFAULT 'R', -- Scroll Bar position
    blk_def_order Varchar2(128)            -- initial ORDER BY clause
-- Table of blocks records --
TYPE TYP_TAB_BLK is table of TYP_BLK index by BINARY_INTEGER ;
TB_Blocks        TYP_TAB_BLK ;
Begin
TB_Blocks(1).blk_name := '...' ;
TB_Blocks(2).blk_name := '...' ;
End ;Search for a PL/SQL tutorial.
